lie itfltnown that l, (leonor: T. Fiemme, l a citizen ot' the United States, anda resi` dent of the city of New York, borough of the Bron, in the county and State of New York. hare invented a new and Improved Illuminating Device, of which the following is a full. clear, and exact description.

The object' of the invention is to provide a new and improved illuminating device more especially designed as an advertising medium for use in the show windows of drug stores. perl'uinery stores and the like, and which forms an attraction for passersby.

ln order to accon'iplish the desired result use is made of a vessel or bottle of diaphanous material and containing a fluid, a series of lignts arranged in the rear of the said vessel, differently colored media between the said lights and the rear of the .said vessel, and means causing,r intermittent turning of the said lights whereby the rays of light emanating from the said light are retracted by the fluid in the said vessel, andtli said fluid 'appears in rapid succession in the various colors of the said media and in the various colors produced by the blendingr ot' the colors of the said media.

practical embodiment of the invention is represented in the accompanying drawing-s forming a part of this specification` in which similar characters of reference indicate correspondingl parts in all the views.

Figure l is a side elevation of the ill|uninating device with the cas-:ing shown in seci tion: Fig. 2 is a front face view of the casing and the incandescent electric lamps! mounted therein; Fig. 3 is a sectionilplan l View of the illuminating device on the line 3-3 ot' Fig. l an'd Fig. 4, is an enlarged sectional plan View of the automatic electric switch for each incandescent electric lamp.

A vessel or bottle A of glass orother suitable diaphanous material and of ovoid or other ornamental is mount-ed on the top and bottom in ca'ps B and B rigidly connected'with each other by rodsl B2. The top cap B is suspended by chainsl C or the like from a suitable overhead support arranged in a window casingr or other structure in which the illuminating device is to be displayed. The vessel A is filled with a Huid preferably Water or other liquid rendered somewhat cloudy by the addition of a electric lamps G, (Jr

suitable substance such as dissolved soap to retard the refraction of the light. he rear port-ion of' the vessel A is provided with means E for the diffusion of light, the said means consisting preferably ofa coating of paint ot' white or other color. The two rear' connecting rods B2 of the mounting 'are en. gaged by lugs F of acasing,r F arranged in the rear of the rear portion of the vessel A, and the said casing F .is open at the front and is in contact at the sides, top and bottom with the vessel A.

Within the casing F is arranged a series of lamps G, G', electric lamps having their sockets attached to the top of the casing F so that the lampe are suspended within the yoisiigr one alongside the other. The lamps G, .1 and G2 are located in close proximity tc the rear portion of the vessel A so that the rays et light emanating from the said lamps are refract ed by the liquid D contained in the Vessel A, the said liquid being illuminated uniformly owing to the rays of light being'dilused in their passage through the ditusing means E on the rear portion of the vessel ji. The

and G2 are Yprovided with bulbs of dierent colors such as red, green and blue, as indicated inthe drawings. Each of the electric lamps G, G and G2 is provided with `an automatic electric switch for periodically flashing each lamp, the said [switch being preferably of the construction in the Letters latentshown and descril'led of the United States, No. 884,514. granted to Andrew H. Miller, on April 14, 1908, and which lamps are now in 'the market. As shown in Fig. 4,' the automatic electric switch consists .essentially of a heater a which actuates the thermodynamic switch b, the lamp filament being indicated b i' The back of the casing F is provided with a suitable door F2 to permit access to the interior of the said casing for placing; the electric lamps in position or removing the same therefrom whenever it is deemed nec essary to do so. The top of the casing F is provided with ventholes Fa to allow circulation of airthrough the casing to lieep A as cool as possible. the casing F is prefforrn a rellecting surthe same and the vessel The interior surface of erably nickel plated to face. y Y lVhen the illuminatingrdeviee is in use and the electric lamps G, G and G2 are burning then the raies of light emanating intermittently from the lamps are refracted G2, preferably incandescent .las

by the fluid D in the vessel and consequently the said fluid appears in rapid succession in the various colors of the bulbs and in the various colors produced by the blend ing ot the colors of the said bulbs. Thus at one time the fluid l) may appear momen tarily green, at another time red and at arr other time blue, according to which of the .lamps (l, G and G2 is burning, While the others are extinguisl'ied; and at another time the liquid may appear in any blended color according; to which or" the two lamps are burning', or in c: all three are burning at the time. as the changes 'trom one color to another are in rapid succession it is evident that a iery attractive display is had.

lt is understood that the arrangement described dii'ferent colored media. are interposed between the vessel A and the correspendingr sources of light, and means are employed to cause the intermittent burning ot the lights to produce the desired eect, which is heightened by a proper ditl'usion ol the rays ot light through the diffusing means ll.

Altlioiurh the vessel .ft-is shown and described as being suspended it is evident Athat it- Inay be otherwise supported in any desired place.

vllaviurr thus described my invention, l claim as new and desire to secure by Letters Patent:

l. ln an illuminating device, the combination of a vessel of diaphanous material, f cloudy liquid lillingl the said vessel, a series ot lights adapted to be intermittently burned and arranged in the rear of the said vessel, diflereutly colored media between the said lights and the rear of the said vessel, whereby the refraction of the rays of light emanating,r irom the said lights is retarded by the cloudy 'particles in the said t'luid, and the said cloudy fluid appears in rapid succession in the various colors of the said media and in the various colorsl produced by tbc bicrulinli ot the colors oi the said media.

2.' Aln an illuminating device, the combination ot' a vessel of diapbanous material, a liquid contained in the said vessel and rendered cloudy by the addition or a substance tending to retard the refraction of light through the said liquid, a casing held on the rear of the vessel and having an open trout into which extends the rear of the said vessel, a series of incandescent electric lamps arranged in the said casing one aloner side the other, the said electric lamps having ditl`erently-colored bulbs and the said electric. lamps beingI adapted to be intermittently burned to produce irregular flashing of the lamp lights, the refraction of the rays of light enianating from the said lamps being,r rntardcd by the retardinp; substance in the liquid, the latter appearingin rapid succession in the various colors of the bulbs and in the various colors produced by the blondine# oic the said bulb colors.

3. ln. an illuminating device, the combination of a vessel of diaphanous material, a liquid contained in the said vessel and vrendered cloudy by the addition 'of a substance and tcrdinf,r to retard the refraction of light through the said liquid, a casing held on the rear of the vessel and having an open 'front into which extends the'rear of thc said vessel, means for removably fastening,l the casing ir nl sition on the said vessel, a series ot' incandescent electric lamps ,arranged in the said casing one alongv side the other, the said electric lamps having ditlcreutly colored bulbs, the colors being primary colors, the said elect 'ic lamps beiner adapted to be intermittently burned to pro# duce irregular flashing of the lamp lights, the refraction ot the rays of light emanatinp; from the said lamp being retarded by the retardinfr substance in the liquid, the latter appearii'ig in rapid succession in the 'furious colors of the bulbs and in the various colors produced by the blending of the said bulb colors.

ln testimony whcrcoi` l have signed my name to this specification in the presence of two subscribing Witnesses.
